  • Patent number: 10725532
    Abstract: Data storage system power shedding for vaulting and/or backup is provided herein. A data storage system can include a processor that executes computer-executable components, at least one memory, and a basic input/output system device that stores respective ones of the computer-executable components executed by the processor. The computer-executable components comprise a power monitor component that monitors an input alternating current power level of the data storage system, a processor management component that causes the processor to transition from a multiple-core operating mode to a single-core operating mode in response to an indication from the power monitor component that the input AC power level has decreased below a threshold, and a backup component that initiates a transfer of data stored by the at least one memory to at least one backup storage device in response to the processor being configured to operate in the single-core operating mode.

  • Patent number: 10719120
    Abstract: A spare capacity status of each of multiple computing systems in a data center is monitored. Temporary workloads are assigned to these computing systems if there exists sufficient additional electrical power supply and capacity on power distribution lines. Thus, computing systems that are typically not productively used, such as those that are about to be decommissioned, have not yet been assigned for normal servicing, are reserved for special circumstances, or that are assigned to services that are currently in low demand, are temporarily used for productive data center purposes.

  • Patent number: 10642337
    Abstract: Micro-idle power in a subsystem of a portable computing device may be actively managed based on client voting. Each client vote may include a client activity status indication and a client latency tolerance indication. Votes are aggregated to provide an aggregate client latency tolerance, which may be used to obtain a set of micro-idle time values. Micro-idle timers in the subsystem may be set to associated micro-idle time values. The micro-idle timers determine whether one or more of the micro-idle time values have elapsed. A power management policy associated with each micro-idle time value determined to have elapsed may be applied to a portion of the subsystem.

  • Patent number: 10642332
    Abstract: In some examples, a controller receives, from a sensor that is part of a device mounted on a moveable platform, measurement data. The controller detects, based on the measurement data, a change in transit motion status of the moveable platform. The controller triggers, in response to detecting the change in transit motion status of the moveable platform, a transition of the device from a first power state to a second, different power state.

  • Patent number: 10635147
    Abstract: The invention provides a detection system and detection circuit for detecting health status of backup power supply module. The detection circuit comprises a boost converter, a controller, and at least one backup power supply module. The boost converter receives an input voltage to generate a first high voltage. When the detection circuit is operated in a detection state, the boost converter is inhibited to output the first high voltage, the backup power supply module can execute a discharging process to provide a discharged energy to a load device, the controller detects a time at which a discharged potential of the backup power supply module is dropped from a first voltage to a second voltage to obtain a discharged time detection value. The controller can know a health status of the backup power supply module by a comparison between the discharged time detection value and a discharged time threshold value.

  • Patent number: 10635158
    Abstract: The present disclosure generally relates to an electronic circuit and method of operating thereof to back up write cache data on DDR memory in data storage devices during an emergency power off (EPO). The method involves using a power management integrated circuit (PMIC), a combo driver and one MOSFET for regulator output. The method involves detecting a voltage value that is below a predetermined threshold value, retracting a write head away from a hard disk drive (HDD), backing up data, and then resetting the HDD after the backup is complete. The backing up and retraction may occur in parallel or in sequence. The method utilizes the spindle back-electromotive force (BEMF) power to have sufficient power to make the backup. If the power from the spindle BEMF is too low, then the retraction is suspended and a high impedance is present to lighten the load until the BEMF recovers before the power on reset. As such, the back-up data is not reset and volatized by a lack of power.

  • Patent number: 10599204
    Abstract: A monitoring system may receive data indicating work performed by a set of computing devices during a given period of time and may receive data indicating an amount of power consumed by the set of computing devices and support systems that support the set of computing devices during the given period of time. The monitoring system may normalize the amounts of work performed by different types of computing devices in the set and determine an aggregate amount of work performed by the set. The monitoring system may also determine an aggregate amount of electrical power consumed by the set of computing devices and support system that support the set of computing devices during the given period of time. A monitoring system may use the aggregate amount of work performed and aggregate amount of power consumed during the given period of time to determine a performance index efficiency for the set.

  • Patent number: 10591951
    Abstract: An array of ultrasonic transducers can be controlled to produce a steerable beam. Beam steering can be skewed by buffer delays in the distribution of a clock signal. The skew can be at least approximately linearized by distributing the clock signal in a diagonal fashion across an array of buffers corresponding to ultrasonic transducer controllers. Potential error in beam steering that can arise from clock skew can be corrected based on the linear tilt.
